John Cage’s Sonatas and Interludes: When the Piano Becomes a Percussion Orchestra

A Listening Map of 50 Piano Works · Article 45

Sonatas and Interludes places screws, bolts, rubber and other materials among piano strings, turning individual keys into distinct percussion colours. Its first question is not what to play, but what this piano now is.

Take an inventory of the prepared piano

Sound type Possible impression
Metallic Bell, gong or brief ring
Dry wood Woodblock, drum rim or impact without sustain
Muted low sound A constrained drumhead
Still piano-like The original instrument has not completely vanished

How to hear sixteen sonatas and four interludes

Do not memorise twenty sections. Compare adjacent pairs for colour combinations, phrase length and repetition. Treat interludes as larger breathing spaces rather than ordinary connectors.

Preparation is not damage

Placement, size and installation of materials belong to the work’s specification; the aim is a controllable new instrument. Different pianos still vary, making each performance an act of instrument-building.

  • Identify four colour families.
  • Hear silence separating impacts.
  • Ask when you forget that the instrument is a piano.
